To a solution of 4-bromo-1,2-dimethyl-3-(1-methylindolin-6-yl)-1H-pyrrolo[2,3-b]pyridine (D28) (85 mg, 0.239 mmol) in 1,4-dioxane (2 mL) was added 1-methyl-1H-pyrazole-3-sulfonamide (D94) (65.4 mg, 0.406 mmol), cesium carbonate (155 mg, 0.477 mmol), Pd2(dba)3 (16.39 mg, 0.018 mmol) and 2-(dimethylamino)-2′-(dicyclohexylphosphino)biphenyl (14.08 mg, 0.036 mmol). The reaction mixture was heated in the microwave at 150° C. for 30 mins. The reaction mixture was filtered through celite washing with ethyl acetate and the resulting solution evaporated to dryness. The residue was purified by column chromatography on silica gel, eluting with a gradient of 0-100% ethyl acetate in cyclohexane to afford a material which was further purified by MDAP (basic condition) to afford the title compound (25 mg). LCMS (A): m/z (M+H)+ 437, C22H24N6O2S requires 436 (acidic).
